Vinyl Single-Hung Window Upvc Classic Design Modern Performance American Style

Our UPVC hopper windows are engineered for superior performance in specialized applications. The top-hinged design

allows the sash to tilt inward from the bottom, creating exceptional ventilation control and weather resistance.

Constructed with multi-chambered, reinforced UPVC profiles, they provide outstanding thermal insulation

and are ideal for basements, bathrooms, and high-rise buildings where traditional windows are not suitable.

Their compact design and airtight seal make them a highly efficient and secure window solution

Superior Weatherproofing: The inward tilt and sealed design excel in preventing water ingress,

making them perfect for rainy climates and basement installations.

Excellent Ventilation Control: Provides secure and controlled airflow, even in tight spaces,

without obstructing curtains.

Enhanced Security & Safety: The inward-opening mechanism is inherently difficult to force

open from the outside. Ideal for ground-level and high-rise applications.

Space-Saving Design: Does not protrude outward or inward, making it the ideal choice for

walkways, alleys, and rooms where space is at a premium.

Energy Efficient: Multi-chambered UPVC frames and double-glazed units ensure high thermal

insulation, reducing energy costs.

Easy Maintenance: The inward tilt allows for easy and safe cleaning of the exterior glass from

inside the room.
